摘要
The lumped component equivalent circuit of an inductor capacitor transformer integrated component (LCT) is deduced from a set of impedance measurements. This circuit allows. the whole electronic behavior of the component, including losses. to be accurately forecast by using standard electronic simulation software. A closer look at experimental data reveals,that several physical phenomena, often neglected, have a strong impact on LCT electrical properties. Dielectric losses in the capacitor and permittivity related losses in ferrite core are among them. To sum up, this paper lists main phenomena to account for in future field computations, it supplies a suitable equivalent circuit that accounts for them and it shows how to extract all its element values from a set of impedances deductible from field computations.
